Compaq r3000 ups drops out while pluged in to a\c power

The ups will work fine indefinitely then for no apperent reason it will lose power on the output plugs and none of the LED's change, if you the cut the a\c power to the unit it will switch to backup and restore power. Then you can restore a/c power to it and it will run indefinitely again and repeat the cycle. The batteries are fresh and it only recently started doing this, it is as if there is some kind of circuit breaker,other than the ones on the back, inside the unit that is letting go prematurely. Only 1 LED is lit on the load bar so it should not be overloaded, I know for sure, from amp measurements, that it is only supplying 4 amps of power normally and 11.7 amps with everything possible on.
Thanks

Did you ever get a resolution to this issue? I have the exact same
problem. Someone advised that I should ensure that the Sleep mode is
disabled through the config but that is already the case. Do you by any
chance have the UPS in a non-air conditioned room where it might be
getting too hot? Secondly, do you have both the battery leads connected
to the battery pack or just one of the pairs is connected?

First of all you should make sure that the UPS is capable of handling the mains voltage from the country you're into now. After that just cut the cable as close as possible to the old mains plug then add a new one - all you need to be sure is which is the ground wire and that is very easy to find out with a simple ohmmeter. When you will go back to the US all you will have to do is to replace the plug.

The Compaq R3000 were rebadged APC ups' and so I would suggest looking in the APC website http://www.apc.com/ and select your country and they will be able to help you out ( possibly a download of the manual and software )

It sounds like the battery is compatible with the ups.
However, APC has excellent free phone support.
I recommend that you give them a call.
Be ready to give them the model number and serial number for your UPS.

start your computer in safe mode (hit F5 key during startup) go into the Administrator account and hopefully it isn't password protected , go to control panel then to user accounts and select the profile you use and remove the password

I have repaired the same.
there are some dycon to protec the circuit in the bottom part of ups that sometimes are broken,
sometimes one plug of the battery is disconnected.
can you give me the software to make shutdown of xp pc when we lost power?

possibly..you have unpluged or dislodge you power cable from the outlet or from the power plug shuye at the back of your ups.. double check all the plug and re plug all your power cables !!!! make sure they are tightly pluged in and firm in their outlets..

You gave no reasons why you thought it was simply a software setting, so I gave you a link below for some management software.
The HP R3000 UPS supports HP Power Management Software (CPM) version 1.8.

In addition the HP R3000 UPS also supports the LanSafe III management software (discontinued).
My first question is: When were the batteries last changed?
If they haven't been changed in 3 or so years, then it's probably low batteries, meaning they are old and cannot take a charge anymore.
